A
good product to break the dormancy of plant ---- Cyanamide
 Brief
Introduction:
 Cyanamide
is a kind of the dormancy-breaking agent, which can
inhibit the action of hydrogen peroxidase in plant and
speed up recycling of PPP of plants to stimulate the
generation of some basic substance of plants, growth
of plants and stop the dormancy of plants. It can cause
the following beneficial effects on treated plants:
advanced budbreak, flowering by 2-4 weeks; more uniform
budbreak; increased percentage of budbreak; shortened
flowering period and reduction in the number of picks.
The treated fruits turn to be bigger, more uniform and
sweeter. Also the harvest of fruits can be advanced
by 2-3 weeks and the yield can be increased. |
The results of application:
| Darong is the first manufacturer of Cyanamide
in China. During the period of 2000-2002, it has made
many experiments of the dormancy breaking on grapes,
cherry and kiwifruits in Ningxia, Shandong, Dalian and
Shanxi etc. In Ningxia, the grapes were treated by cyanamide
with three concentrations of 1.5%, 2.5% and 3.5%. The
cyanamide was sprayed with motorized knapsack sprayer.
The results showed: the budbreak could be advanced by
17-19 days, fruit growth by 16-18 days and fruit maturity
by 14-16 days. The percentage of budbreak could be increased
by 5.7%, 13.3% and 10.3% respectively and meanwhile
the yield increase was 10.5%, 17.4% and 15.1%. The net
income per mu could be up by RMB236-341. In city of
Talian of Shandong, the grapes were treated with cyanamide
with three concentrations of 1.0%, 3.0% and 5.0%. The
results showed: advanced flowering periods by more than
8 days, increased weight of fruits by 6.8-7.1 grams,
the yield increase by14.3%. Comparison in color, hardness
and content of solid substance proved that breaking
dormancy by applying cyanamide solution on grapes could
not degrade the quality of fruits. |

Timing of application:
The time of application depends mainly
on the agroclimatic conditions, the crop and the objective
of use.
1) In order to increase the
percentage of budbreak, treating 2 to 3 weeks prior
to the time of natural budbreak onto the dormant canes.
(The time of budbreak varies year to year)
2) For advanced budbreak, in subtropical conditions,
it is usually applied 45 to 30 days prior to the time
of natural budbreak. Under tropical conditions it is
usually applied immediately after pruning.
3) Crops in the shelter, such as cherry, grapes, can
be treated with cyanamide 2-6 weeks prior to the time
of natural bud break. |
Precautions:
1) Wear protective clothing
and eye shield when applying cyanamide.
2) Drink wine or eating food with alcohol are forbidden
24 hours before and after the operation.
3) Clean eyes and mouth with clean water, wash face
and hands with soap after operation.
4) Cyanamide is a kind of weedicide and defoliating
agent. Be careful not to spray on other plants nearby.
5) Avoid late frost when applying cyanamide.
6) Harmful to bees, don't spray on the plants.
7) Avoid direct sunlight, and temperature for storage
is under 20. Don't store it together with acid and alkali.
Keep it away from food or the places that the children
can reach. |
